Arctic Cooling reveals its Liquid Freezer 120, 240 and 360 coolers are compatible with AMD's upcoming Ryzen Threadripper processors. As far as I know, Arctic Cooling is the first company to announce which of its existing coolers are compatible with Threadripper.

The 120mm version of the Liquid Freezer is rated at up to 250W while the 240mm and 360mm editions can handle a TDP of up to 300W.
